Multipurpose support assembly for outdoor games or shelter constructions

ABSTRACT

The invention relates to a support assembly to which outdoor games equipment (net, elastic or rope) and folding panels used in shelters, exhibition stands, for decorative or advertising purposes or as general notice boards, can be attached. The assembly is made up of a container (1) and a shaft (5), the container being filled with water, sand or gravel and including a handle (2) and a hole (4) through which the shaft is housed; and the shaft comprising elements nesting into each other which can be placed one on top of the other. The support assembly can be made of plastic or of a light alloy.

FIELD OF THE INVENTION

This Invention concerns a multipurpose support assembly for playground equipment; miscellaneous shelter constructions (rain huts, wind-breaks, sun screens etc.); safety boundaries (particularly for monitoring recreation areas) (notably on beaches); construction of exhibition-stand partitions; safety barriers around civil engineering sites; erection of decorative panels or advertising boardings, or notice boards of any kind.

BACKGROUND OF THE INVENTION

Within the stated applications (except in cases of hard surfaces) it is common practice to employ shafts or uprights fixed into the ground; the high weight and large dimensions of such uprights do not make for easy transport; a maximum of fixed rings also are required for attaching the desired equipment (rope, elastic cord etc.), and construction of the upright itself requires further hardware (nuts and bolts).

The subject of the Invention is to provide a multipurpose support assembly obviating the above disadvantages, suitable for all types of ground, of low weight, easily transportable, adjustable, with no bolting systems, to allow rapid installation through simple stacking of the various structural elements, and rapid attachment of accessories; in sum, a system producible in various dimensions tailored for the end-user (children or adults) and of a weight tailored for the type of accessories to be supported. This device is equally designed as an instructional tool for children of even the earliest ages, in team sports as volley ball or individual sports such as high-jumping or shooting. The same device can also be employed for educational games, as, for example, by attaching signs to the said supports when teaching the Highway Code.

SUMMARY OF THE INVENTION

This Invention covers a series of superimposable parts forming a support allowing attachment of games accessories (nets, skipping ropes, elastic cord for high-jumping, pennons or flags), as well as miscellaneous panels and shelter elements.

General low weight, and the compactness of the multipurpose support and its accessories (stowed in a simple hand-carried bag) make for easy transport, even by small children.

The support consists of modules of various shapes placed on or nesting one in the other. The basic module is formed by a container which can be filled with water, sand or gravel to give the necessary weight for supporting the various games equipment, shelter elements or panels. Where required, several basic elements can be stacked to give the necessary weight to counterbalance the size and weight of the various accessories.

Each module used in the support is produced as a single injection- or blow-molded plastic part. Other lightweight high-strength materials can be used such as aluminum, giving the required features of rigidity, strength and above all, lightness to ensure implementation by children.

DETAILED DESCRIPTION OF THE INVENTION

A complete support assembly is illustrated in FIG. 1:

Basic module (1) is a container whose upper part contains filler-opening (3). The container is penetrated vertically by sleeve (4) which receives module (5), onto which the container is seated. Housing (6) in the container bottom receives shoulder (7) mounted on the end of module (5). The container bottom also has housing (8) dimensioned to receive filler-opening (3), hence allowing stacking of several containers (9).

One side contains handle (2) formed by a housing above and below a central part left integral with the container side.

Module (5) forms the first element of the shaft (or "prop") and is fitted with boss (7) which houses in container (1). The other end contains bore (10) which has sufficient depth to receive rod (11), which is strong enough to form a sound interface with another module (12).

Module (12) is another part of the prop, penetrated by bore (13) which has sufficient depth to receive rod (11), which is strong enough to form a sound interface with other modules (13). Depending on the application (games etc.), the length of this module can be varied.

FIG. 2 represents an accessory designed for the "elastic skipping" game and comprising three parts: sliding part (14) (two off), crossbar (15) (two off), and elastic cord (16). Slide (14) is split down one face to form a two-part "clip" allowing upward and downward movement (height adjustment) along the prop. The side opposide the split side has a shoulder containing an opening into which another part (crossbar stem) is fitted, to receive stub (17) on the crossbar.

Crossbar (15) is designed to space the two parts of elastic (16); the elastic fits in a groove along one side of the crossbar. Hence this accessory enables a lone child to play the elastic game, whereas three children are normally involved (two using their legs to hold the elastic apart).

Slide (14) also can be used for height-marking when used with graduated shafts.

FIG. 3 represents an accessory designed for high-jumping and consisting of a flat scale (18) with sleeve (19) fixed along one side. The part fits over support mast (12). This part is perforated (20) at one-centimeter centers along each long side, hence forming the graduations and a position mark for the elastic, which is attached to the scale at the selected hole. A number (21) is scribed alongside each hole.

FIG. 4 illustrates three accessories for installation at the top of shaft (13):

1st accessory (22) is a rod topped by a target;

2nd accessory (23) is a rigid bar topped by a ring for attaching a chain or skipping rope via a swivel;

3rd accessory (24) is a rod topped by a notice or sign board.

FIG. 5 illustrates a textile or plastic-film panel (25) (two thickness of heat-welded material forming pockets (26) between the two sides); the pockets receive lathes (27) providing rigidity while allowing the assembly to be folded fan-wise. Two side pockets or tunnels (28) are slid over the shafts, to extend the panel.

The device covered by the Invention has applications in the field of leisure, safety, decoration, communication and teaching.
